LXVIII. THYJ1ELEA5. 
[ Drapetes . 
Colenso. Middle Island : abundant on the alps, ascending to 5000 ft., from Nelson, 
Bidwill, etc., to Otago, Sector and Baclianan. This is, I think, the same with the Tasma- 
nian Z>. tasmanica of my ‘ Flora Tasmania,’ which has also been found on the Australian 
alps by Mueller. 
2. D. Lyailii, Hook. f. FI. N. Z. ii. 336. — D. muscosa, FI. N. Z. i. 
223, not Lamarck. Stems short, densely tufted, rarely with long straggling 
branches. Leaves ovate-oblong, obtuse, ciliated at the tip. Perianth almost 
campanulate. 
Middle Island : Nelson, Wai-au-ua valley, Tracers ; Southern Alps, Sinclair and Haast ; 
Otago, lake district, alpine, Hector and Buchanan ; Southern Island, Lyall. A very dis- 
tinct plant from I). Bieffenbachii, to which it has been reduced by Meisuer, of different 
habit, with shorter, broader, closer-set leaves, and shorter, broader perianth. 
Order LXVIII. SANTALACEiE. 
Trees shrubs or herbs. Leaves usually alternate, quite entire, exstipulate. 
Flowers usually small, very inconspicuous, in heads cymes or spikes, herma- 
phrodite or unisexual. — Perianth wholly or partially superior; lobes 3-6, 
persistent or deciduous, valvate. Stamens as many as and inserted on the pe- 
rianth-lobes ; filaments usually very short ; anthers 2-celled. Ovary inferior or 
superior, ] -celled; style usually short, simple or 3-fid; ovules 3-5, pendulous 
from an erect central placenta. Fruit a 1-seeded nut or berry, indehiscent. 
Albumen fleshy ; embryo usually terete and small ; radicle superior. 
A widely-diffused Order in various parts of the globe, temperate and tropical. 
Trees or shrubs, leafless. Flowers in minute spikes ....... 1. Exocarpus. 
Trees. Leaves long. Flowers in axillary cymes 2. Santalum. 
1. EXOCARPUS, Labillardiere. 
Shrubs or trees, with naked, twiggy, leafless branches, bearing scales at the 
ramifications, rarely leafy. Flowers minute, green, in axillary spikelets or 
clusters, hermaphrodite or unisexual. — Perianth of 4-6 spreading, deciduous 
lobes. Stamens 4-6, short, inserted on the base of the lobes ; filaments 
glabrous. Disk 5-lobed. Ovary superior, fleshy; style very short, conic; 
stigma subcapitate ; ovules not ascertained. Nut oblong, seated on the 
swollen drupe-like tip of the peduucle or base of the perianth. Embryo 
minute, cylindric ; cotyledons small. 
An Australian, New Zealand, and Pacific Island geuus. 
1. E. Bidwillii, Hook. f. FI. AT. Z. i. 223. t. 52. A small, rigid, pro- 
cumbent shrub, 8-16 in. high, much branched; branches stiff, short, grooved, 
terete, leafless, with minute triangular scales at the bases of the branches. 
Flowers 8-10, in short puberulous axillary spikes. Perianth 5- or 6-parted. 
Stamens 5 or 6. Nut black, drupaceous; peduncle red. 
Middle Island: Warrau mountains, Bidwill-, river beds of the Kowai and Waitald 
rivers, alt. 2000-3500 ft., Haast ; Hurumui mountains, Travers. Closely allied to the 
E. humifusa of Tasmania, and probably a variety of that plant, but the flowers are more 
spiked and 5- or 6-merous. I think two plants are confounded in the ‘ Tasmanian Flora ’ 
under E. humifusus, one the true plant of Brown, resembling this, the other much smaller, 
with compressed stems, which I originally called E. nanus.
